I don't want to turn this thread into a book club, but for any poster who wants to understand where all this rage and consternation at the RF is coming from, Norman Baker's book is the best place to start.
The "concrete facts" are, in a nutshell: since the 1930s (actually way before, but let's not get into that here), the House of Saxe-Coburg and Gotha (who the fuck are they anyway?) have swindled MILLIONS of pounds from British taxpayers and have engineered the "constitution" to twist and invent the rules, ensure their own legal immunity and amass wealth beyond anyone's imagination.
The part of NB's book about the Duchy of Cornwall is just eye-watering. It's basically an organised crime racket. Read the book if you don't believe me.
PC has no legal right to do what he's doing but because he's audit-immune, FoI immune and basically untouchable, he gets away with it.
Even though the RF are just the same as Maxwell, Philip Green, that Royal Bank of Scotland guy and any other tax-dodging swindling corporate asset stripper you care to name, there is no point in trying to get them legally, because they play on their "royal" status to pretend they are above the law.
def. "Racketeering is a type of organized crime in which the perpetrators set up a coercive, fraudulent, extortionary, or otherwise illegal coordinated scheme or operation (a racket) to repeatedly or consistently collect money or other profit." = Duchy of Cornwall.
